LED Lighting - COBs, Engines, Modules

LED lighting has become increasingly popular over the past decade and is now often used in many areas including commercial, residential, and industrial settings. LEDs are particularly popular due to their energy efficiency and long lifespan. One type of LED lighting technology is COBs (Chip on Board), which is a design of packaging multiple LED chips into one package. CST-90-W57S-C12-GN200 is a COB with an interchangeable engine featuring a high CRI and excellent lighting performance. In this article, we will discuss the application field and working principle of this COB.

Application Field

CST-90-W57S-C12-GN200 is widely used for retail, commercial, and industrial lighting applications. This COB can be used to light display cabinets, staircases, medical examination rooms, exhibition halls, showrooms, urban lighting, office buildings, shop window lighting, and residential homes.

Working Principle

CST-90-W57S-C12-GN200 is composed of multiple LED chips placed on the same chip. The chips are connected to a circuit board to form an integrated circuit, which is connected to a power supply. This type of COB operates on a principle known as current sinking. When the COB is connected to power, the LED chips receive constant current, which produces light. The current through the LED chips is determined by the control unit, which is adjusted according to the needs of the application. For example, if a specific level of illumination is not achieved, the control unit can lower the current to the LED chips, which will produce lower lighting levels. The operating temperature of the COB also needs to be monitored in order to ensure that the light output is not compromised. This can be done with the help of a thermal management system, which constantly monitors the temperature and adjusts the current to the LED chips accordingly.

Conclusion

In conclusion, CST-90-W57S-C12-GN200 is a COB designed for lighting applications in a variety of settings. It operates on a principle known as current sinking, which is controlled by the control unit. The COB also needs to be monitored to ensure that it is operating at its optimal performance level. With its high CRI and excellent lighting performance, it is a popular choice for many applications.
